WATCH: Vampire Weekend Play Letterman

The Ivy Leaguers kick off the Contra era with a performance of "Cousins."

After premiering their entire new album, Contra, online via MySpace yesterday, NYC indie rockers Vampire Weekend took to the small screen last night, stopping by The Late Show with David Letterman to perform album track “Cousins.” Watch the video below!

Their appearance ended with the customary handshake from Letterman, and while killing time before the show ended, the cagey host fumbled his announcement of Contra’s release date — “In stores today? Tomorrow? Next week!” — much to frontman Ezra Koenig’s chagrin.
